Unusually high uptake of fluoro-2-deoxy-D-glucose on PET scanning of a benign paravertebral mass.
Positron emisson tomography (PET) is a noninvasive and highly accurate method for identifying malignant tumors. In our practice we have chosen a Standard Uptake Value (SUV) of 3.5 to distinguish between benign and malignant lesions. We describe a patient with a paravertebral mass which on PET scanning showed a SUV of 7, thereby clearly being identified as a malignant tumor. Subsequent open biopsy of the lesion, however, revealed benign connective tissue.
